4-Nitrophenyl N-acetyl-α-D-glucosaminide is used as a substrate for determining the hydrolysing activities of pnp-glycopyranosides in the gut of larval and adult Psacothea hilaris.[1]

4-Nitrophenyl N-acetyl-α-D-glucosaminide is used as a substrate for analysing β-hexoaminidase activity at 37°C and analysed at 405 nm.[2]

Three methods of quantifying chitinase activity were compared. The activities of crude chitinases of 10 bacterial isolates from different environments were estimated in terms of (1) the release of p-nitrophenol from the chromogenic chito-oligosaccharide analogues, p-nitrophenyl-beta-D-N,N'-diacetylchitobiose, p-nitrophenyl-N-acetyl-beta-D-glucosamine and p-nitrophenyl-beta-D-N,N',N"-triacetylchitotriose, (2)
Glycosidase-promoted hydrolysis was performed in a microreaction channel. The result was compared with the reaction in a micro-test tube. Transgalactosylation on p-nitrophenyl-2-acetamide-2-deoxy-beta-D-glucopyranoside was also examined in a microreaction channel, because transglycosylation is a useful method for oligosaccharide synthesis. We examined

Transchitooligosylation from (GlcNAc)5 to the 4-position of PNP-GlcNAc was efficiently induced through lysozyme catalysis in an aqueous solution containing methanol with a high concentration. Use of the aqueous methanol system in this reaction not only guaranteed solubility of PNP-GlcNAc substrate
